A Functional Magnetic Resonance Imaging (fMRI) Study of Expectancy on Acupuncture Treatment Outcomes in Knee Osteoarthritis (OA)
Summary
The results of the proposed experiments will directly inform clinicians who treat patients with osteoarthritis of the knee about how to maximize the benefits of acupuncture treatments. And because the experiments specifically asks the question of what is the relation between a patient's expectation of how a treatment will relieve their pain and the outcome of the treatment, the results will potentially inform care givers about all treatments for osteoarthritis and other chronic pain disorders. We hypothesize that acupuncture treatment will produce clinically significant analgesia as indicated by lowered sensory ratings of noxious stimuli and endogenous knee pain.

Medical and Biotech [MESH] Definitions
Osteoarthritis, Knee
Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (Crenshaw, Campbell's Operative Orthopaedics, 8th ed, p2019)
Acupressure
A type of massage in which finger pressure on specific body sites is used to promote healing, relieve fatigue, etc. Although the anatomical locations are the same as the ACUPUNCTURE POINTS used in ACUPUNCTURE THERAPY (hence acu-), no needle or other acupuncture technique is employed in acupressure. (From Random House Unabridged Dictionary, 2d ed). Shiatsu is a modern outgrowth that focuses more on prevention than healing.
Acupuncture Analgesia
Analgesia produced by the insertion of ACUPUNCTURE needles at certain ACUPUNCTURE POINTS on the body. This activates small myelinated nerve fibers in the muscle which transmit impulses to the spinal cord and then activate three centers - the spinal cord, midbrain and pituitary/hypothalamus - to produce analgesia.
Acupuncture Points
Designated locations along nerves or organ meridians for inserting acupuncture needles.
Acupuncture, Ear
Acupuncture therapy by inserting needles in the ear. It is used to control pain and for treating various ailments.
